Chapter 10: Merlina's True Intentions

The D-Avengers have just beaten the Black Knight of Camelot, King Arthur. Shortly after his defeat, they noticed that Arthur has dissolved into dark matter, leaving nothing but his scabbard behind.

"What the…?" Sonic said, confused, while he grabs the scabbard.

"Um, okay, so, who else is confused here?" Weiss asked the group, which they all raise their hands to agree.

"We should talk to Merlina about this." Blake suggested.

"Right. Where exactly?" Yang asked.

"She said she would meet us at Castle Camelot." Caliburn reminded her.

"Right, thanks."

"Alright then, next stop: Camelot Castle." Ruby said as they all head course to Castle Camelot, but before she leaves, she notice Sonic hasn't moved an inch. "Sonic, come on. We need to go see Merlina."

Sonic snapped out of whatever train of thoughts he was in. "Oh…yeah, I'm coming." He said, catching up with Ruby.

"You okay?" She asked in concern.

"Yeah, just…confused." Sonic replied, trying to figure out why King Arthur disappeared like an ordinary Underworld goon.

"Let's go see Merlina. She might know something." Ruby suggested.

'I hope so.' Sonic thought before catching up with the others.

At Castle Camelot, Merlina is standing next to tree, until she is surrounded by the Knights of the Round Table and their apprentices.

"We have orders from the King. Have you any last words?" Lancelot asked her.

Merlina spoke up, "Your king was nothing more than an illusion my grandfather conjured up."

What she said confused everyone there. "An illusion? I don't get it." Arc said, looking confused.

"Merlina, what are you talking about?" Nikos asked her.

"You've better start explaining, Merlina." Percival demanded her.

Just then, they all hear someone shouting her name from above. "Meeerrrliinnnaaa!" shouted Sonic, with he and the others dropping in-between Merlina and the other Knights.

BGM End

"It's Sonic and Team RWBY." Lie noticed.

"Hey guys, how're you doing?!" Valkyrie asked them, excited to see her former rivals again.

Gawain then noticed the scabbard in Sonic's hand, "You! How did you come by that scabbard? Where is the King!?"

Percival holds back Gawain before he does something rash, and to hear what Sonic might have to say, "Wait!"

"This was all he left after he disappeared in a puff of smoke," Sonic told Merlina, showing her the scabbard he picked up from the dead King of Camelot. "Just like one of the Knights of the Underworld…"

"Merlina, do you anything about what's going on?" Ruby asked her.

BGM-Sonic and the Black Knight OST-Merlina: Her Wicked Smile

Merlina then closed her eyes and started explaining with a mysterious smile, "There was never any King Arthur." She said

"Huh?"

The young wizard then slowly approached the confused hedgehog. "Well done and thank you, Avengers." She takes the scabbard from Sonic's hand and puts it right next to her chest. "With this scabbard I can erase my grandfather's greatest mistake." She is then surrounded by a sinister pink aura that causes her hair to untangle and flow like crazy because of her absorbing the scabbard's great power.

"What?" Sonic responded, now even more confused.

"I shall make this kingdom eternal…" Merlina strikes the ground with the scabbard that releases a menacing blast of dark energy, slowly leaking across the land.

"What is going on?!" Ruby asked trying to shield herself from the blast.

"Everyone, get back!" Caliburn shouted.

"He's right! Let's get out of here, people!" Lancelot shouted, quickly grabbing onto Arc and Blake and starts running into the castle.

Gawain does the same, grabbing Lie and Yang, while Percival grabs Valkyrie and Weiss since Nikos can keep up, just leaving Sonic and Ruby to follow with their own speed.

As they all are leaving the area, Percival stops for a moment to see a dark energy ball in the sky, forming a terrifying opening in the clouds. Then, the castle starts to collapse and transform all around them, slowly into a more dark sinister version of itself.

BGM End

BGM-Sonic and the Black Knight OST-Escape from the Destruction

With Sonic and Ruby in the lead, everyone is running for their lives as they try to escape the collapsing castle. While most of them are dodging the debris, Sonic and Ruby are destroying all the stones falling on top of them with high speed slashes, smashing through a wall that has already collapsed on itself, stopping for a second to see if everyone is behind them before they could continue their escape.

BGM End

BGM-Sonic and the Black Knight OST-For the Kingdom and Its People

Everyone was able to escape from the castle just in time before it fully collapsed and transformed into something else, some "dark hollow." They watch the castle from a distance, wondering what to do next.

"So, it was all part of Merlina's plot..." Lancelot said as he stoically looks back at the castle from the distance with his knightly allies.

"It just keeps spreading, far and far into the kingdom." Nikos said, looking worried for herself and the people of the kingdom.

"It's only a matter of time before the kingdom is consumed." Lie said.

"So, it's all over for us, isn't it, Lie?" Valkyrie asked him.

"Yeah, just like our village, but on a much bigger scale and nothing to stop it." Lie replied, making her all sad and depressed,

Arc angrily punches a wall next to him. "I can't believe it. I was training to become a great knight, just like King Arthur. Now what I am supposed to do when the whole world is ending?"

"Arc…" Nikos whispered.

It was then Gawain's turn to feel helpless. "Gah! The Knights of the Round Table…Must we simply stand and watch our kingdom's ruin!?"

"Gawain…" Percival said.

Just then, Sonic and Team RWBY appeared on top of a cliff next to them. "You guys can't give up, not now." Ruby told them.

"She's right. Is that the best that chivalry of yours can do?" Sonic asked them.

"How dare you!" Gawain said in anger.

"Watch it, knucklehead." Yang told him.

"You guys can't give up, not when there is still hope left." Weiss told them.

"How can you guys stay so calm with all of this happening?" Arc asked them.

"We've had…a few world-ending threats that happened to us recently." Blake told him while rubbing the back of her head, remembering events like the Goblin War or the most recent Spider-Island mess.

"Oh."

"Listen, it's like I said before...Isn't there more to being a knight than serving a king?" Sonic reminded him.

After he said that, Nimue appears from a portal on the ground. "Sir Sonic is right. And there is still time if you act now." The portal then shows a map with four spots that surround the castle. "Use the sacred swords to form a barrier around the castle."

Blake, Yang, and Weiss throws back their swords back to their original owners. They then pick up their respective swords. Percival was the first to speaks up, "For the kingdom and its people!"

All of the Knights of the Round Table and their apprentices raise their weapons to the sky as they clash with one another, "For the kingdom and its people!"

"We're counting on you!" Sonic told them.

Percival looks at Sonic. "Sir Sonic! What will you and Team RWBY do!?"

"Once the barrier's up, we'll look for a chance to jump in." Sonic replied.

"Surely you jest!?" Percival responded, thinking he's crazy to perform something so stupid.

Ruby spoke up with a smile, "Nah…It's just how we roll." She said, giveing Sonic a fist pump.

Percival smiled and points her rapier upward, "Fare thee well. We, too, shall fulfill our appointed task."

BGM End

Everyone left to go to their respective areas to activate the barrier. Sir Lancelot and his apprentice, Sir Arc, traveled through the Shrouded Forest to find one of the barrier stones. Along the way, they battled against Underworld creatures and Grimm that are now under Merlina's control. After all of that, they finally arrived at the stone pillar.

BGM-Sonic and the Black Knight OST-The Barrier

"This must be it." Arc said as they look around the place they are at.

"Indeed. This must be the barrier stone." Lancelot responded, smashing his sword into the stone. The stone wall then depicts some sort of writing, in which Lancelot reads aloud. "'This stone is but part of the ring that sealeth the Dark Hallow.'"

"Dark Hollow? Do you what that is, Sir Lancelot?" Arc asked.

"No, I don't." He replied as he puts his hand on his chin. "What is Merlina up to now?"

At the Great Megalith, an area next to the Titanic Plain, Sir Gawain and Sir Lie have just arrived at the second barrier stone.

"Here it is." Gawain said, smashing his two swords into the stone. The stone wall then depicts another sort of writing that Gawain could easily read. "'When the sacred sword pierces stone, so shall return the power.'"

Lie spoke up, "Is it referring to Excalibur, the greatest of all the sacred swords?"

"Maybe. The King wore its scabbard but I never saw the sword itself..." Gawain replied

"Hmmm. I wonder where it is." Lie pondered.

At the Cauldron, which is a highly active volcanic area, Sir Percival, Sir Nikos, and Sir Valkyrie have arrived at the third barrier stone.

"This must be it." Percival said as she too smashes her sword into the stone. The stone wall then depicts another sort of writing.

"Our fate is now your hands, Sir Sonic..." Percival said.

"Don't forget about Team RWBY." Nikos reminded her.

"Oh yes…of course." Percival nodded.

"Let's hope they give Merlina a good beating. Mostly on the legs." Valkyrie said, which prompts Nikos and Percival to look at her strangely.

BGM-Sonic and the Black Knight OST-Dragon Slayer

At the Dragon's Lair, Sonic and Team RWBY are trying to find the barrier stone. Unfortunately, they came across a little problem.

"Aw!" Ruby said, dodging an incoming fireball coming from the big red dragon in front of them.

"Why do we have to go to the place where there is a big dragon trying to eat and burn us alive!?" Weiss asked while trying to attack the underworld creatures while also avoiding the dragon's fire ball attacks. "I'm sure the others aren't dealing with anyone like this!"

"Enough complaining, Weiss! Let's just end this, fast!" Blake told her just as Sonic jumped off from attacking the crystal on top of the dragon's head.

"Sheesh, I agree. Let's just finish this off already!" Sonic said. He then noticed the pillar next to the dragon. "Wait, I have an idea! Ruby, Weiss, Blake, can you distract the dragon for a little while?"

"Sure, Sonic." Ruby said as she, Weiss, and Blake distract the dragon.

"Alright then, Yang. You and I are going to break down that pillar over there." He told her while pointing to the pillar next to the dragon.

"Alright, let's do this!" She said, approaching the pillar so they could break it down, which starts to fall on the dragon. "Tiiimmmmbbbeeer!" She shouted as the pillar falls on top of the dragon, defeating it.

"Great job!" Sonic said, giving Yang a high-five.

"Now is not the time to celebrate. We still have a kingdom to save." Weiss reminded them.

"Right, let's go people!" Sonic said as they run deeper into the cave.

BGM End

BGM-Sonic and the Black Knight OST-The Barrier

The team was able to find the last barrier stone needed in order to stop the spread of Merlina's influence.

"This must be it." Sonic said as he smashes his sword into stone, in which the stone wall depicts a sort of writing.

"What does it say?" Ruby asked.

"I don't think it matters now." Blake replied.

"We're running out of time. Let's go, knights!" Caliburn told them.

"Here goes!" Sonic said as they run back the route they came.

BGM End

BGM-Sonic and the Black Knight OST-Into the Dark Hollow

Back with Nimue, she is using her portal as a map to see that the barrier is up. Unfortunately, it would seem that it is not working, as the Dark Hollow continues to spread.

"Oh, no! The barrier is too weak!" Nimue said, looking worried that their plan to delay the kingdom's destruction has failed.

Outside, Sonic and Team RWBY are staring at Merlina's Castle from afar.

"Now's the time." Sonic said.

"Indeed." Caliburn responded

"Let's end this." Ruby said as her team is ready to barge into the castle.

"Here we go!" Sonic said as they all head towards the dark castle for the final confrontation to save the world.

BGM End

BGM-Sonic X OST-Sonic Drive

Sonic: I'm Sonic, Sonic the Hedgehog. We've finally arrived where Merlina is staying. She plans to use the scabbard's power to make this world eternal.

Ruby: Well, we can't just sit here and her do that, right?

Sonic: Of course not. What good is a world that goes on forever? Merlina needs to learn that, even if it means we take her down.

Ruby: Well then, let's finish this right guys?

Everyone: Right!
